Abstract

La présente invention concerne un projecteur et un procédé de commande d'un projecteur, avec lesquels la sécurité du projecteur peut être améliorée. Le projecteur comprend une partie de stockage destinée à stocker une liste de destinations de connexion indiquant des dispositifs auxquels le projecteur est autorisé à se connecter, et une partie de commande de communication pour, lors de la connexion à un autre dispositif par l'intermédiaire d'un réseau, la commande de la connexion à l'autre dispositif sur la base de la liste de destinations de connexion. Par exemple, la présente technologie peut être appliquée à un projecteur qui est connecté à un autre dispositif par l'intermédiaire d'un réseau.
